HYDRoCAREioN-BURNER.

SPECIFICATION forming part of Letters Patent No. 753,825, dated March 1,1904.

Application filed August 31,1903.

To aZZ whom) it may concern:

Be it known that I, Lnoros E.' COLEMAN, a citizen of the United States,residing atSanta Ana, in the county of Orange and State of California,have invented a new and useful Hydrocarbon-Burner, of which thefollowing is a specication.

This invention relates to-hydrocarbon-burners of that class which areemployed for heating purposes and which are specially adapted to b edisposed for operation in the fire-boxes of ordinary cooking or heatingstoves.

. My invention has for its object to provide a device of this classwhich shall be simple in construction and inexpensive 4and which may atthe same time be easily manipulated, which shall not be liable toaccumulate soot or dirt, and in which the accumulation of carbon withinthe retort of the device shall be rendered inocuous by the peculiarconstruction of the device, whereby such accumulations may be removedand disposed of fromtime to time. i

With these and other ends in View my invention consists in the improvedconstruction, arrangement, and combination of parts, which will behereinafter fully described, and particularly pointedy out in theclaims.

In the accompanying drawings, Figure 1 is a vertical sectional view ofmy improved hy- `drocarbon-burner, showing the same applied in operativeposition in the fire-chamber of an ordinary cook-stove. Fig. 2 is asectional detail view taken onthe line 2 2 in Fig. 1.

. Corresponding parts in the several figures are ndbited by similarnumerals of refer- @IlQ/e,

1 designates the retort upon my improyed burners, which is ofinverted-frustum shape, the sides of said retort being upwardly divergedand said retort' being provided with a closely-fitting cover 2, whichmay be integral therewith. The lowerend of the retort has a closureconsisting of a bushing 3, comprising a screw-threaded portion 4 and ahead 5, projecting beyondl said screw-threaded porti0n,'so as to formafiange 6. The lower end of the retort is reinforced, asV shown at 7,and interiorly screw-threaded to be engaged by the screw-threadedportion 4 of the bushing.

Serial No. 171,449. (No model.)

' Awasher 8 may beinterp'os'ed between the 'flange 6 and the reinforcedportion 7 to form a tight joint.-

The bushing 3 has a central screw-threaded perforation through whichextends the feedpipe 9, the lower end of which is connected by an L 10with a pipe 11, leading to the source of supply. Thepipe 9 may beextended any desired distance into the retort, said distance beingeasily regulated, owing to the fact that the said pipe 9 is exteriorlyscrew-threaded throughout its entire length, thus enabling any desiredadjustment to'be easily effected.

The top 2 of the retort has an opening 12, in which is tted an lL 13,with which the vapor-pipe 14 is suitably connected. Said vaporpipe 14 isconnected by an L 15 with the vertically-disposed burner-pipe 16, theupper end of which is tightly closed by a cap 17, whileI the side ofsaid burner-pipe is provided with a minute opening 18. This openingfaces a spray-plate 19, the lower edge of which'has a notch 20, wherebyit is adjusted, straddling the vapor-pipe 14 and leaning against the L13, as will be clearly seen in Fig. 1. In this manner the saidspray-plate may be supported with suflicient security and yet in such amanner as to enable it to be easily detached when 'l it shall be desiredto disassemble the parts.

21 designates a bed-plate, which is provided with a surrounding fiange22, which takes the place of the grate usually employed in a stove. Inother words, in order to apply my invention the grate is removed fromthe stove and the bed-plate21, which is made 'of a size and shape tocorrespond with the grate, is mounted in place thereof upon the supportsusually provided for such grate. It follows from this that thebred-plate used in connection'with my invention may be made of anydesired size and shape, provided, of course, that it is provided withthe ange 22 and also with a depression23, whereby it is, likewisecharacterized. This vdepression is forthe reception of any possibleoverflow, which is likewise confined by the flangev 22. The bed-plate isprovided with an opening 24, which is of such an area that the retort '1when seated therein, as shown in Fig. 1, shall project for the greaterpart of its height below' said bed-plate. This IOO is an importantfeature of my invention, inasmuch as I thereby avoid any possibility ofoverheating the lower part of the retort and the rapid formation ofcarbon resulting from such overheating. As will be seen, however,-

the lower part of the retort is of ample size to accommodate anyimpurities that may accumulate therein for a long time, and it willfurther be seen that by removing the bushing at the bottom of the retortany such impure accumulations may be readily removed. Let it here benoted that the bushing is not exposed to the heat of the iiame evolvedby the burner and that consequently there is little or no chance of itsbecoming fastened in such a manner, as to render its removal difcult.

25 in the drawings designates a portion of an ordinary stove in thefire-box of which my improved burner is disposed for operation. From theforegoing description, taken in connection with the drawings heretoannexed, the operation and advantages of my invention will be readilyunderstood. In order to apply my improved hydrocarbon-burner to alstove, it is only necessary to remove the grate from such stove andsubstitute in place thereof the bed-plate 21, which, as abovestated,`has

placed in position in the bed-plate, the pipe' 1l leading' to the sourceof oil-supply is connected up, and the device is now in condition foroperation. It is obvious that a valve, as 26, is to be provided upon theoil-pipe in order that the supply of oil maybe regulated. In order tostart the llire, the supply-valve is slightly opened, thus permittingthe oil to overiiow the feed-pipe within the retort, the latter beingmeanwhile heated by means of a torch or other suitable means until theoil is vaporized, when it will ascend through the passages 12, 13, 14,15, and 16, escaping through the port 18, from which it is projectedagainst the spray-plate 19, the .spray thus projected being easilyignited, said spray being commingled with air supplied through theordinary draft-opening in the stove, which said draft-opening isdisposed above the bed-plate 21. The intensity of the i'iame may beregulated by means of the valve 26, and the fire may be extinguished byclosing the valve.

I have in the foregoing described a simple and preferred construction ofmy improved hydrocarbon-burner, and I desire it to be nnderstood that Ido not limit myself to the precise structural details herein set forth,but reserve the right to any changes, alterations, and modificationswhich may be resorted to within the scope of my invention and withoutdeparting from the spirit or sacrificing the utility of the same. Thusit may be mentioned that, if desired, -a plurality of retorts andburners may be mounted in a single bedplate; but this has not beenspecifically shown., for the reason that it would amount simply to aduplication of the burner which forms the subject of this presentinvention.

Having thus described my` invention, I claim- 1. In a device of theclass described,the combination of a bed-plate having an opening, aninverted-frustum-shaped retort seated in said opening and projecting'for the greater part of its height below said bed-plate, a bushingforming a closure for the lower end of the retort, a feed-pipeadjustably connected with said bushing, and connecting means betweensaid feed-pipe and the source of supply.

2. In adevice of the class described, a bedplate having an orifice, aninverted-frustumshaped retort seated in said orifice and projecting forthe greater portion of its height below the bed-plate, a bushing forminga closure for the lower end of the retort,a feedpipe connectedadjustably with said bushing and extending upwardly into the retort,connecting means between the lower end of the said feed-pipe and thesource of supply, a permanent closure for the upper end of the retort, avertically-disposed burner-pipe having an opening in the side thereof,connecting means between said burner-pipe and the retort, and aspray-plate disposed in front of and adapted to receive the dischargefrom the opening in the burner-pipe.

3. In a device of the class described, the combination of a retort, avapor-pipe extending from the latter, a vertically-disposed burnerpipeconnected with said vapor-pipe and having an opening in the sidethereof, and asprayplate disposed in front of said opening and having anotch in its lower edge engaging the vapor-pipe.

4. In adevice of the class described, a retort having a permanentclosure at its upper end, an L connected with said closure, a vapor-pipeconnected with the L, a vertically-disposed burner-pipe connected withsaid vapor-pipe and having an opening in the side thereof, and aspray-plate notched in its lower edge to straddle the vapor-pipe andcontacting' with the L connected with the top of the retort,being.thereby supported upon said retort in a position to receive thedischarge from the oritice in the burner-pipe.

In testimony that I claim the foregoing as my own I have hereto aiiixedmy signature in the presence of two witnesses.
